Re: nas server

It sounds like you want to replace your existing 72GB drives with 146GB ones... First check that you have a RAID 1 array, download the HP Array configuration utility for your OS and check the RAID level, once confirmed make a backup of all your data (to be safe) then simply pull one drive, insert the new one and wait for it to finish the rebuild process, you can check the rebuild process with Array config utility, once it's complete, do the same with the other hard drive.

Now you can select your logical drive from within ACU and extend it's size. Of course your current partition will remain the same size, now you need to 1) Create a new partition for the remaning hard drive space or 2) Use something like partition magic to modify the partition size.
